i have a 03 zr440 snopro and im going to be using it as a trail sled i have a couple updates that i still have to do to it one being some kind of support for the rear suspension and another for the bell crank houseing or something like that just wondering if anyone can shed some light on that for me as to how critical it is and how big of a job it is??? any info would be great

thanks in advance
